and other perishable articles; and consists of open spaces so arranged that air may circulate freely through the ice from the chamber below, for the purpose of condensing, refrigerating, and purifyng said air, the condensing being directly on the ice, the under surfaces of the caps and gutters being dry, thereby entirely doing away with all manner of absorbents, sweating fioors, and drippans; also having no need of outside ventilation for purifying the air contained in the refrigerator.

First, a room of large dimensions, A, strong enough to support six feet of ice over the whole surface, surrounded on all sides by'a good nonconductor of heat.` Second, .joists B B are placedhorizontally across the room ahoutafoot apart. Between each of these j osts are' placed narrow metal gutters C C. Qver each joist are placed metaLcaps D D, Figs. 2 and 4, projecting over the gutters, but leaving a large space for air. Over these caps is an open grate, E E, Fg. 3, alsohaving spaces for air,

and upon which the ice is placed. a is a small drainage-trough for carrying the water from the ice outside the building.

I make no claim to the general Construction of the house as I am aware this is not new; nor do Iclam condensing and refrigerating inclined metallic surfaces combined with dripgutters, as I amaware such have been used; but

I claim as my invention- The combination of the metal grate, caps, and gutters over the entire surface of the refrigerator in such a manner as to expose the entire under surface of the ice t o the upper surface of the air contained in the refrigerator, substantially and for the purpose hereinbefore set forth.
